How to read XLI
Roman numerals are read left to right, largest value first, adding as you go. Scanning XLI one group at a time gives a running total that lands on 41:
| Read | Worth | Running total |
|---|---|---|
| XL | 40 | 40 |
| I | 1 | 41 |
The one place that scan can trip you up is the pair XL. A smaller letter sitting in front of a larger one is subtracted, not added, so you have to read those two letters as a single unit rather than one at a time. Treat XL as one group and the rest of XLI falls into place.
